• Locate and unpack a Nautel Part # 207-8251-01 “Copper Tube”. Align its L-shaped
brass end with the other copper tube and again use the “Combiner Tube Jig” to hold
the copper tubes in place while securing them together using two M8 captive screws.
Remove the jig.
• Carefully slide the full-length copper tube assembly in and guide the end through the
large holes in the “Teflon Plates” between the cabinets until it reaches the opposite end
of the control cabinet. Secure the end of the copper tube assembly to the copper angle
using an M12 bolt, Belleville washer and flat washer, torqued to 275 in-lbs (31 N-m).

Step 15 (see Figure 3.5 on page 3-11 ), using three sets of M8 hardware on the side and an
M12 bolt, Belleville washer and flat washer on the end. Torque the M12 bolt to 275 in-lbs
(31 N-m).
19. Install current probe A67 at the output cabinet end of the “lower” copper tube installed in
Step 16 (see Figure 3.5 on page 3-11 ), using three sets of M8 hardware on the side and an

(31 N-m).
20. Re-install the four side cover plates removed in Step 14 .
21. Locate four combiner splice plates (Nautel Part # 207-8140-09), packed in the transmitter.
22. Install the combiner splice plates, as shown in Figure 3.5 on page 3-11 , between the existing
combiner covers in each cabinet. Install two plates between the upper and lower combiner
covers in cabinets 1 and 2. Install two plates between the upper and lower combiner covers
in cabinets 2 and 3. Secure each plate using M8 hardware already in the combiner covers.
